Which one of the following is an example of an acid-base reaction?A. HCI + KOH --> H2O + KCl

B. 2CuS + 302 –>2CuO + 2SO2

C. S8 + 802 —> 8SO2

D. C3H8 + 5O2 —> 3CO2 + 4H2O

Answer : The temperature will be, 150 K

Explanation :

Charles' Law : This law states that volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

    (At constant pressure and number of moles)

or,

where,

= initial volume of gas = 2.0 L

= final volume of gas = 1.0 L

= initial temperature of gas = 300 K

= final temperature of gas = ?

Now put all the given values in the above formula, we get the final temperature of gas.

Therefore, the temperature will be, 150 K

Answer:

There are two correct choices:

• Real gas particles have significant volume
• Real gas particles have more complex interactions than ideal gas particles.

Explanation:

Ideal gases are not real; ideal gases are a theoretical model used to confere a better understanding of gas properties.  This model permits to predict the behavior of the gases using the ideal gas law, which is valid under certain conditions (mainly low pressure and high temperature).

Kinetic molecular theory states these basic assumptions for gases:

•    Gas particles are in constant, random motion.

•    Gas particles  move in a straight line until they collide with another particle or the walls of the container.

•    Gas particles are much smaller than the distance between particles, so most of the volume of a gas is therefore empty space, and the particles are considered to occupy no space.

•    There is no force of attraction acting on gas particles nor between them

•    Collisions are perfectly elastic, meaning that no energy is lost durign collisions.

Those conditions are not perfected matched by real gas particles, since real gas particles do occupy a volume and interact with each other, this is real gas particles have significant volume and  have more complex interactions than ideal gas particles.

Answer

Option 1 - Real gases are always hotter than the ideal gases.

Explanation

Gases that are different from ideality are called real gases because they are always hotter than the ideal gases as they are flying past each other at an extremely high speed that creates kinetic energy. Whereas idea gases have absolutely elastic collisions, this is as it has a valuable theory because it embraces the perfect concept of original gas law.

Answer

Option 2 - Real gases particles have significant volume.

Explanation

Real gases have significant volume because they have a high temperature and have a higher volume as compared to ideal gases. There is a general gas theory that is composed of several randomly crossing point particles. Several gases, for example, nitrogen, oxygen, and hydrogen can be manipulated like ideal gases within a generous immunity of the idea gas.

Answer

Option 3 - Real gases particles are smaller than an ideal gas.

Explanation

Real gas particles are smaller than ideal gas particles since they have a volume and are made up of molecules or atoms that typically take up some space than the ideal atoms. The ideal gas pattern manages to break at moderate temperatures level or greater pressures point when intermolecular energies and molecular mass enhances to be significant.

Its False, because in the formation of an ionic compound, an atom gains or loses an electron.
